1. Applications
Radio waves and Broadcasting waves

2. Radio waves
A kind of electromagnetic light energy with wavelengths anywhere from a few centimeters to several kilometers long.
Radio waves can be used to carry signals to and from spacecraft and Earth.

3. Radio wavelengths
radio waves are the longest out of all the waves in the electromagnetic spectrum
The shortest radio waves are about 100 yards.

4. Frequencies
*Radio frequencies represent a subsection of electromagnetic energy found on the energy spectrum.
*Signal strength differentiates the different types of radio waves, and all radio waves fall between mm and 100km in distance, and 3 KHz to 300 GHz in frequency.

5. How Radio and light waves relate
Both radio and light waves travel at the same speed
260,000 miles per second.

6. AM/FM radio AM- broadcasted with a single specific carrier frequency.
*more range
*1 MHz, 300 m wavelength
FM - broadcasted with a specific amplitude.
*better quality
*100 MHz, 3 m wavelength
